To all whom it may concern.-

Be it known that I, WVILLIAM B. RUSH, a citizen of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented certain new'and useful Improvements in Corn- Planter Check- Rowers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to corn-planter checkrowers of that class in which a tappet-carrying wire or cord, which is stretched along the path to be traversed by the corn-planter, is used to actuate the check-row devices, and to that particular type of this class of checkrowers in which the tappet wire or cord crosses the planter; and the invention consist-s in constructions and combinations, hereinafter described and claimed.

In the accompanying drawings,which illustrate my improvements, Figure l is a front Fig. 7 is a detail.

elevation. -Fig. 2 is also a front elevation,

differing from Fig. 1, as hereinafter described. Fig. 3 is a top plan. Fig. 4 is a front elevation of one of the forked levers. Fig. 5 is a front elevation of the other forked lever. Fig. 6 is an enlarged top plan of parts of the device. Fig. 8 is arear elevation of parts of the device.

Referring to the drawings by letters, the same letter indicating the same part in the different figures, Arepresents a bar on which the working parts of the check-rower are mounted. This bar A is adapted, as in this class of check-rowers, to be secured transversely on the planter, and may be so secured in any desired manner and-in such position that the lever a maybe connected at its lower end with the ordinary seed-slide connectingbar, a. As herein shown and described, that side of the bar A which is toward the front part of the planter is shown in front at Figs. 1 and 2, and at the lower or bottom side of Fig. 3.

be moving in the direction of the arrow at At Figs. 1 and 3 the planter is assumed to;

Fig. 3, and at Fig. 2 to be moving in the op-f posite direction.

The operation of the pulleys B in guiding and directing the tappet wire 0 across the planter and to the forked levers, as the planter is moved across the field, need not be herein" described, as it is well known to those skilled in the art of making or using check-rowersof this type. a l p D D are forked levers, pivoted at their lower ends to the bar A. v D Din their normal positions incline in oppo- The forked levers site directions to each other, and rest against stops a a, respectively.

The lever D is formed in two separate parts, d d, the longer andforked part (I and the shorter part (1, both journaled on the same stud-journale;

The partd has a projecting ledge, e, which,

comes in contactwith the part d and swings it on the journal 6,- and with the part d when the part d isswung toward the lever .D, as

shown by dotted lines at Fig.2. The lever .D is formed in two parts, d" d the longer part d j ournaled on the stud-journal e" at its lower end, and the part c.journaled on the same stud at its mid length portion. The part d has a projecting ledge, c, which comes in contact with the upper end of the part d, and swings the part 11 with the part (1 when said part (1 is swung toward the lever D.

F is a shaft journaled in suitable bearings transversely on the bar A.

G is a segment gear-wheel journaledloosely on the shaft F and its outer face provided with ratchet-teeth g.

H is a clutch mounted on the shaft F so as segment I carries a crank-pin, i, from which the clutch H, and thereby the shaft F and a connectingrod, J, extends to the upper end of the part dof the lever D. Another connecting-rod, J, extends from the crank-pin z" to the lower end of the part d of the lever D.

K is a plate from which a retractingspring, 7c, extends to and is connected with the 0011- necting-rod J at j, and another retractingspring, It, extends to and is connected with lever a. The plate L has two teeth, Z,on which a gravitating detent, m, operates to prevent return or backward movement of the shaft F from any cause, but especially from the friction of the segment Gin its return or backward movement.

As shown at Figs. 1 and 3, the planter is supposed to be moving in the direction of the full-line arrow shown at Fig. 3, and hence the tappets 0 cross the check-rower in the direction shown by the dotted-line arrow at said Figs. 1 and 3, and while moving in the direc tion last named the tappets c act only on the lever D, and not on the lever D. Each tappet a coming in contact with the forked lever D, as shown by full lines at Figs, 1 and 3,

swings said lever over to the position shown by dotted lines at Fig. 1, and permits the tap pet to escape in the usual manner. The movement of thelever D, last described, swings its.

part 61, connecting-rod J, and segment-gear plate I into the respective positions shown by dotted lines at Fig. 1. The segment-gear I, being in gear with the clutch H, as shown at Fig. 1, its last-described movement will give plate L, a half-rotation, and this semi-rotation of the plate L will swing the lever a in one direction of its throw by means of the crankpin Z in the slotted upper end of said lever a. \Vhen the tappet c escapes from the forked lever D, as hereinbefore described, thesprin g is will retract the rod J, and thereby draw the lever D back into its normal position by acting on its part 61, which will act on its part d. The retraction of the rod J last described 1 will also swing the plate I back to its normal position, (shown by full lines at Figs. 1, 2, and 3,) and this return movement of the plate I will give a return or backward movement to 1 the gear G. As the gear G makes the return movement last described, it does not act on the clutch H nor shaft F, as the inclined sides of its ratchet-teeth 9 press against the inclined sides of the ratchet-teeth on the clutch H, and thus force the clutch H outward on the shaft F, as shown at Fig. 6, and permit the segment I to return to its normal position while the Hence, the swlnglng movement of the lever D will impart an intermittingly-rotating movement to the shaft F, and thereby a swinging movement to the lever a. Vhen the lever D is swung by a tappet, c, as hereinbefore described, it will move the rod J by the movement of the segment I, and this movement of the rod J will swing the part (2 of the lever D back to the position shown by dotted lines at Figs. 1 and 4; but this movement of the part (2 will not move the part (I, which, if moved, would interfere with the movement of the lever D. The next movement of the lever D effects the same results on all the parts except on the lever a, which it swings in an opposite direction to its last movement, and thus the tappets c, acting on the lever D alone, as the planter moves in one direction across the field, will actuate the seedslides of the planter. \Vhen the planter is turned at the end of the row,and commences a new bout in the opposite direction from that last described, the tappets c then move across the planter in the direction shown by the arrow at Fig. 2, and act alone on the lever D, and not on the lever D. As each tappet swings the part cl of the lever D backwardly, it carries the part d with it, as shown at Fig. 2 by dotted lines, and thereby, actuates the rod J, segment I, and other parts ;leading to the seed-slides of the corn-planter in the same manner as the lever D, and hence need not be any more fully herein described. When the lever D is swung by a tappet, it moves the rod J and the part 12 of the lever D, as shown by dotted lines at Figs. 2 and 5, but does not move the part 1, the movement of which would interferewith the movement of the lever D. Thus, as the planter moves in one direction across the field, the tappets c act on the lever D, and as the planter moves in the opposite direction the tappets act on the lever D, and the movement of either lever does not move the other, while both act upon the same oscillating plate. The pulleys it serve to guide the tappet-wire and to insure its contact with the forked levers.

What I claim as new, and desire to secure by Letters Patent, is V 1. In a check-rower, in combination, the forked lever D, formed of parts cl cl, forked lever D, formed of parts (1 03, rods J J, and an oscillating plate, to which the rods J J are hinged or journaled, substantially as and for the purpose specified.
